摘　　要：南水北调排洪渡槽由于受地形限制,进出口布置比较复杂.通过对南水北调中线应急供水工程排洪渡槽设计,对进出口渐变段(喇叭口)布置、排洪渡槽纵坡确定和槽身多纵梁、多侧墙结构型式的适用条件等分析,为同类建筑物设计提供参考.Since the limitation of the topographic condition, the layout of the intake and the outlet of the flood discharge aqueduct (for the emergency water supply project for the Beijing-Shijiazhuang section on the Mid-route of South-to-North Water Transfer Project) is more complicated. Through the design of the aqueduct, the analyses are made on the arrangement of the transition sections of both the intake and the outlet, the determination of the longitudinal slope of the aqueduct and the suitable conditions for the multi-longitudinal slope and multi-longitudinal beam with multi-sidewall of the aqueduct body, which provide the simliar structures with the available references.
